Abstract: TEA1601 PHILIPS voltage across the resonant capacitor Cr. This capacitor is acting at the same time as blocking element , it is rectified and smoothed by the output capacitor. Mains isolation Mains input circuit , bootstrap capacitor which is used for the floating supply of the high side driver. During start-up, the voltage across the frequency capacitor C17 is zero to have a defined start-up. The output voltage of the , via the soft start option of the TEA1610 via soft start capacitor C31. Soft start can also be done

Further more the QR Flyback runs at the borderline between discontinuous (DCM) and , the resonance capacitor CR, parasitic output capacitor COSS of the MOSFET and the winding capacitance , become zero the next interval begins. In the fourth interval the energy stored in the drain capacitor CD , switch will be opened and the start-up current source is enabled to charge the capacitor at the VCC as , start capacitor CSS between the sense pin and the sense resistor is charged to 0.5V. Once the VCC
